From f5d59230ec26aa5e8b59e9f4a4d288703a737479 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 31 Jan 2024 21:31:01 +0100 Subject: [PATCH] r8169: simplify EEE handling We don't have to store the EEE modes to be advertised in the driver, phylib does this for us and stores it in phydev->advertising_eee. phylib also takes care of properly handling the EEE advertisement.
